Royal Mosa, a mid-sized Dutch ceramic tile manufacturer, has no published company-level GHG data despite energy-intensive operations. Strengths lie in circular product design and third-party certifications; critical weaknesses are absence of emissions targets, no Scope 1/2/3 disclosure, and unverified claims around renewable energy and water management.
